The zero-shot baseline primarily fails by copying input text verbatim instead of translating, while T5-small full fine-tuning shows moderate improvement but suffers from oversimplification and limited vocabulary. The FLAN-T5 LoRA model successfully balances medical accuracy with accessibility, though it occasionally struggles with complex medical conditions (10-15% of cases) and rare anatomical terminology (15-20% of complex cases). The superior performance of FLAN-T5 LoRA can be attributed to its instruction-tuning foundation, parameter-efficient adaptation preventing overfitting, and larger model scale providing better medical language understanding. ## Future Improvements From 324446c1a9e4341058e77d79316a846c43353806 Mon Sep 17 00:00:00 2001 From: Nathan Chung Date: Sat, 18 Oct 2025 12:17:35 +1000 Subject: [PATCH 109/112] chore: minor adjustment to readme, adding a summary --- recognition/layrad-flant5-lora-nchung/README.md | 2 ++ 1 file changed, 2 insertions(+) diff --git a/recognition/layrad-flant5-lora-nchung/README.md b/recognition/layrad-flant5-lora-nchung/README.md index 46f3c279f..9026b368e 100644 --- a/recognition/layrad-flant5-lora-nchung/README.md +++ b/recognition/layrad-flant5-lora-nchung/README.md @@ -454,6 +454,8 @@ The following plots demonstrate the training progression and model performance: The FLAN-T5-base LoRA model significantly outperforms both baselines, achieving 69.6% ROUGE-1 compared to 44.4% for T5-small full fine-tuning and 31.7% for zero-shot.

The superior performance of FLAN-T5 LoRA can be attributed to its instruction-tuning foundation, parameter-efficient adaptation preventing overfitting, and larger model scale providing better medical language understanding. +Our strongest model is FLAN-T5 base with LoRA. The gain over T5-small full fine tuning reflects both the instruction-tuned base and the parameter efficient update, not LoRA alone. We fixed a held out test split and selected checkpoints only on validation ROUGE-Lsum. Decoding used beam search with a length penalty. The remaining errors are mostly rare condition names and anatomical mix ups.

Instead of updating all 248M parameters, LoRA freezes the pre-trained model weights and injects small, trainable low-rank matrices into the Transformer architecture³. This approach is highly effective, as research has shown that LoRA is competitive with full fine-tuning in high-data scenarios and excels in low-data and cross-lingual transfer settings⁴. ### LoRA Configuration -- **Rank (r):** 8 - Low-rank adaptation dimension -- **Alpha:** 32 - LoRA scaling parameter (alpha/r = 4.0) +- **Rank (r):** 8 - The rank determines the expressivity of the adapter. A rank of 8 is a widely used and empirically validated starting point that provides an excellent balance between performance and efficiency⁵ +- **Alpha:** 32 - A scaling factor for the LoRA update.

Our manual review of generated examples aligns with these findings, revealing several key patterns: + +### Critical Error Types + +**Factual Inconsistency (Hallucination):** This is the most critical error type, where the model generates statements not supported by the source text.

This aligns with findings that LLMs can struggle with nuanced medical language. + +**Propagation of Source Errors:** Radiology reports can sometimes contain errors from speech recognition software (e.g., "The lungs nuclear" instead of "the lungs are clear").

The zero-shot baseline primarily fails by copying input text verbatim instead of translating, while T5-small full fine-tuning shows moderate improvement but suffers from oversimplification and limited vocabulary. The FLAN-T5 LoRA model successfully balances medical accuracy with accessibility, though it occasionally struggles with complex medical conditions (10-15% of cases) and rare anatomical terminology (15-20% of complex cases). The superior performance of FLAN-T5 LoRA can be attributed to its instruction-tuning foundation, parameter-efficient adaptation preventing overfitting, and larger model scale providing better medical language understanding. Our strongest model is FLAN-T5 base with LoRA. The gain over T5-small full fine tuning reflects both the instruction-tuned base and the parameter efficient update, not LoRA alone. We fixed a held out test split and selected checkpoints only on validation ROUGE-Lsum. Decoding used beam search with a length penalty. The remaining errors are mostly rare condition names and anatomical mix ups.

While some errors remain in complex medical terminology and rare conditions, the overall performance represents a significant advancement in automated medical text simplification. - -The parameter-efficient LoRA approach proves more effective than full fine-tuning, suggesting that maintaining the pre-trained model's general capabilities while adding task-specific adaptations is crucial for this domain. This finding has important implications for medical AI applications where both accuracy and efficiency are critical. diff --git a/recognition/layrad-flant5-lora-nchung/src/dataset.py b/recognition/layrad-flant5-lora-nchung/src/dataset.py index e0d6b21a1..a49b68cb8 100644 --- a/recognition/layrad-flant5-lora-nchung/src/dataset.py +++ b/recognition/layrad-flant5-lora-nchung/src/dataset.py @@ -175,6 +175,7 @@ def add_prompts(example): # Create expert-to-layperson translation prompt # This prompt instructs the model to translate medical jargon into plain language + # The format follows instruction-tuning patterns for better model understanding input_text = f"Translate this expert radiology report into layperson terms:\n\n{expert_report}\n\nLayperson summary:" return { @@ -214,7 +215,7 @@ def preprocess_function(self, examples: Dict, tokenizer: AutoTokenizer) -> Dict: handling of variable-length sequences with padding.
